Pete Bacon Darwin f690a4e0af fix(ivy): ngcc - do not analyze files outside the current package (#30591)
Our module resolution prefers `.js` files over `.d.ts` files because
occasionally libraries publish their typings in the same directory
structure as the compiled JS files, i.e. adjacent to each other.

The standard TS module resolution would pick up the typings
file and add that to the `ts.Program` and so they would be
ignored by our analyzers. But we need those JS files, if they
are part of the current package.

But this meant that we also bring in JS files from external
imports from outside the package, which is not desired.
This was happening for the `@fire/storage` enty-point
that was importing the `firebase/storage` path.

In this commit we solve this problem, for the case of imports
coming from a completely different package, by saying that any
file that is outside the package root directory must be an external
import and so we do not analyze those files.

This does not solve the potential problem of imports between
secondary entry-points within a package but so far that does
not appear to be a problem.

Pete Bacon Darwin 42036f4b79 refactor(ivy): ngcc - pass `bundle` to `DecorationAnalyzer` (#30591)
Rather than passing a number of individual arguments, we can
just pass an `EntryPointBundle`, which already contains them.

Pete Bacon Darwin 869e3e8edc fix(ivy): ngcc - infer entry-point typings from format paths (#30591)
Some packages do not actually provide a `typings` field in their

Pete Bacon Darwin 7c4c676413 feat(ivy): customize ngcc via configuration files (#30591)
There are scenarios where it is not possible for ngcc to guess the format
or configuration of an entry-point just from the files on disk.

Such scenarios include:

1) Unwanted entry-points: A spurious package.json makes ngcc think
there is an entry-point when there should not be one.

2) Deep-import entry-points: some packages allow deep-imports but do not
provide package.json files to indicate to ngcc that the imported path is
actually an entry-point to be processed.

3) Invalid/missing package.json properties: For example, an entry-point
that does not provide a valid property to a required format.

The configuration is provided by one or more `ngcc.config.js` files:

* If placed at the root of the project, this file can provide configuration
for named packages (and their entry-points) that have been npm installed
into the project.

* If published as part of a package, the file can provide configuration
for entry-points of the package.

The configured of a package at the project level will override any
configuration provided by the package itself.

Pete Bacon Darwin 7186f9c016 refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921)
To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).

For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.

The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.

You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.

Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.

All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:

* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.

All ngcc and ngtsc source and tests now use this virtual file-system setup.

JoostK 6fbfb5a159 feat(ivy): ngcc - recognize static properties on the outer symbol in ES5 (#30795)
Packages that have been compiled using an older version of TypeScript
can have their decorators at the top-level of the ES5 bundles, instead
of inside the IIFE that is emitted for the class. Before this change,
ngcc only took static property assignments inside the IIFE into account,
therefore missing the decorators that were assigned at the top-level.

This commit extends the ES5 host to look for static properties in two
places. Testcases for all bundle formats that contain ES5 have been added
to ensure that this works in the various flavours.

A patch is included to support UMD bundles. The UMD factory affects how
TypeScripts binds the static properties to symbols, see the docblock of
the patch function for more details.

Pete Bacon Darwin 0c3bb6a731 fix(ivy): ngcc - capture entry-points in top-level path-mapped folders (#31027)
The `EntryPointFinder` computes the base paths to consider
when searching for entry-points. When there are `pathMappings`
provided it works out the best top level base-paths that cover all
the potential mappings.

If this computed basePath happens to coincide with an entry-point
path itself then we were missing it.

Now we check for an entry-point even at the base-path itself.

Paul Gschwendtner 2b4d5c7548 fix(ivy): ngcc should process undecorated base classes (#30821)
Currently undecorated classes are intentionally not processed
with ngcc. This is causing unexpected behavior because decorator
handlers such as `base_def.ts` are specifically interested in class
definitions without top-level decorators, so that the base definition
can be generated if there are Angular-specific class members.

In order to ensure that undecorated base-classes work as expected
with Ivy, we need to run the decorator handlers for all top-level
class declarations (not only for those with decorators). This is similar
to when `ngtsc` runs decorator handlers when analyzing source-files.

JoostK 271d2b51a9 fix(ivy): ngcc - prevent crash for packages without "main" property (#30950)
When determining the module type of a bundle pointed to by the "main"
property, ngcc needs to read the bundle to figure out if it is CommonJS
or UMD format. However, when the "main" property does not exist ngcc
would crash while determining the path to the main bundle file.

This commit fixes the crash by checking if the "main" property is present
at all, before attempting to derive a full path to the bundle file.

JoostK 9d9c9e43e5 feat(ivy): static evaluation of TypeScript's `__spread` helper (#30492)
The usage of array spread syntax in source code may be downleveled to a
call to TypeScript's `__spread` helper function from `tslib`, depending
on the options `downlevelIteration` and `emitHelpers`. This proves
problematic for ngcc when it is processing ES5 formats, as the static
evaluator won't be able to interpret those calls.

A custom foreign function resolver is not sufficient in this case, as
`tslib` may be emitted into the library code itself. In that case, a
helper function can be resolved to an actual function with body, such
that it won't be considered as foreign function. Instead, a reflection
host can now indicate that the definition of a function corresponds with
a certain TypeScript helper, such that it becomes statically evaluable
in ngtsc.

Previously the same `Renderer` was used to render typings (.d.ts)

This commit splits out the typings rendering from the src rendering.
To achieve this the previous renderers have been refactored from
